Fire investigators are asking for the public’s help in solving a murder and ensuing arson in Warren last week.

The state Fire Marshal asked for anyone to come forward with knowledge of how Lori Wishart, 41, was killed and who set fire her 461 Park Ave. S.W. home after she was killed.

A reward of up to $5,000 is being offered for assistance leading to prosecution.

“It is imperative that individuals come forward,” State Fire Marshal Larry Flowers said in a statement. “Investigators want to hear from anyone who saw something out of the ordinary at or around the time of the fire. Any piece of information could be useful to investigators.”

Investigators believe Wishart was killed from asphyxiation. Her body was pulled from the burning duplex on Friday. Crews were called to the building around 1:30 p.m. and found Wishart’s body in a first-floor bedroom.

Investigators said someone set the house on fire to cover up the murder.

Neighbors not wanting to go on camera said the victim’s ex-husband owned the building and was in the process of renovating the upper floor.

Fire officials said the building is not totally destroyed and that most of the damage was pretty self-contained to the front of the bottom floor.

Anyone with information is asked to call the State Fire Marshal’s Fire & Explosion Investigation Bureau at 1-800-589-2728.
